Download EXT Series Manual

EXT pumps are installed near the water feature with the intake pulling from a pre-filtered source, such as a Pondless Waterfall Vault and the discharged water sent to wetland filters, waterfalls, or jets.
See diagram below.

Optional Plumbing Kits Available
Includes fittings, flanges, valves, and hardware to install the EXT pump at the perimeter of the pond’s edge.

It is important to set up the plumbing properly with the EXT pumps. Improper plumbing setups can lead to failure or damage to the pump. We recommend an Aquascape EXT Pump Plumbing Kit. The EXT Pump Plumbing Kit provides all the necessary fittings and valves to make the EXT pump easy to install, prime, and operate. Once primed, the pump can be turned on and off without priming if water remains in the suction line.
